funreg: Functional Register I/O using modern C++funreg provides a functional approach to interacting with registers.The library includes support for memory-mapped registers; however, other typesof registers can be supported through creating a simple access interface.A unique feature of this library is its ability to handle multiple registeroperations with a single function call; these operations will be mergedtogether so that the register is only read and written once.Registers may also be organized into groups. These groups can similarly receivea list of operations, which will be directed the to the appropriate registersfor the same single-read-single-write process.For example, LEDs can be controlled by a microcontroller with a single call:cppLEDS::modify<LED1::set, LED2::clear, LED3::set>();...no matter if the LEDs use different registers, or if any of them arecontrolled by an external circuit rather than a built-in IO peripheral.See GUIDE.md for a walk-through of the available functionality.Feature overviewDefine registers of any size, at any address, with optional custom access interfaceDefine register masks to name the bits of registersDefine register groups so ease programming (e.g. define an RTC group to work with all real-time clock registers at once)Make modifications through groups, masks, or the registers directlyRequirementsC++20GCC or Clang with some optimization enabled (O1, O2, O3, Os).
